Palatine raphe

The palatine raphe (also median palatine raphe^[1]) is a raphe of the oral cavity. It is a narrow, slight midline ridge extending anteroposteriorly across the palate, from the incisive papilla anteriorly to the palatine uvula posteriorly.^[2] Beneath the raphe, the submucosa is absent.^{[2][3]: 637}

Anatomy

The palatine raphe is a midline tendinous band of the palate.^[1]: 114

Relations and attachments

The raphe is a surface feature overlying - and indicating - the intermaxillary suture, and median palatine suture.^{[1]: 114-115}

The greater palatine foramen may be palpated on either side about half way between the palatine raphe, and the palatal gingival margin of the 2nd or 3rd upper molar tooth.^{[1]: 59, 220}

The palatine raphe serves as an attachment for multiple muscles: the palatoglossus muscle arises from the posterior portion of the raphe; the levator veli palatini muscle and (the tendon of) the tensor veli palatini muscle insert into the raphe.^{[1]: 114-115}
